Dr A. Vallecchi received the Laurea (M.Sc.) degree (summa cum laude) in electronic engineering from the University of Florence, Italy, and the Ph.D. degree in applied electromagnetics from the University of Salerno, Italy. After completing his PhD, he was a research associate with the Laboratory of Antennas and Microwaves, University of Florence. In 2008 he joined the University of Siena, Italy, as a postdoctoral research fellow. From 2008 to 2010, he was contract professor for the course “Optical components” at the School of Engineering, University of Siena. In 2013 Dr Vallecchi was awarded a Marie Curie Research Fellowship at the University of Sheffield, UK.
Since August 2015 he has been with the Department of Engineering Science, University of Oxford, UK. In 2019 and then again since Michaelmas Term 2020 he has been a tutorial lecturer in Engineering at St Hugh's College, University of Oxford, Oxford.
